Someone on Lemmy wrote, a little over a year ago I think, that lead ossifies in the bones and then gets released into the blood as bones soften with age. This then affects the brain and might explain why older people have seemingly sudden personality changes. I think about this often.

It is one of the processes of lead poisoning yes. Lead is mistaken for Calcium and stored in your bones.

There's some studies that look into this and its effects on mental health of all stripes. I'm certain in the coming decades there'll be more as the boomers start suffering and dying.
